STEPHEN ANDREWS, OF NEV YORK, N. Y.

ARIVIOR FOR TIRES.

Application filed January 3, 1921.

To all whom it may concern:

Be it known that I, STEPHEN Annnnws, a citizen of the United States,residing at New York, in the county of New York, and State of New York,have invented new and useful Improvements in Armors for Tires, of whichthe following is a specification.

This invention relates to protectors or armors for pneumatic tires.

Some of the objects of the present invention are: to constitute a shellor carcass of sections of comparatively greater invulnerability than thecarcass of the ordinary shoe forming a part of an ordinary pneumatictire, for the protection of the shoe; to form the shell or armor ofsections which are connected together end to end for the relativeyielding action of the said sections; to yieldingly connect the saidsections together in such a manner that by virtue of their construction,the sections will afford a substantially smooth traction surface. l/Viththese and other objects in view the invention resides in the particularconstruction and the relative arrangement of parts hereinafter morefully described and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation illustrating the application of the armorof the present invention to a pneumatic tire.

Figure 2 is a fragmentary perspective view showing the disposition ofthe bands which connect the sections from which the armor is formed.

Referring now more particularly to the drawing for details, it will bemanifest that, the armor of the present invention includes amultiplicity of sections 10 each of which is identical as toconstruction in that each has formed therein ways or openings 11 and 12.The ways or openings extend from one end to the other in each section10. The opening 11 extends through the tread portion, whereas theopenings 12 of each section extend through the side portions thereof.When the sections 10 are arranged end to end. forthe completion of thearmor, the openings of the different sections register with each other.The sections 10 are connected together by the employment of a flat band13 of stout and elastic material, and cross-sectionally round bands 14of stout and elastic material. The band 13 is passed through the opening11 of each section 10 Serial No. 434,567.

which goes to make up the armor, and the bands 14 are passed through theopenings 12 of each of the said sections. When the prescribed number ofsections 10 have been c011- nected together, the opposite ends of thebands 13 and 14: are vulcanized, to make continuous elastic connectingmeans for the allowance of relative movement of the sections withrespect to each other. When arranged over the shoe of a pneumatic tirethe sections may yield with the tire to any irregularities orobstructions of the road surface. Through the longitudinal axis of thetread portion, each section is similar in shape and thickness, thus whenthe sections are connected together as explained, the periphery of thearmor will be substantially smooth irrespective of the anti-skiddingsurface that each of the sections may have.

The sections 10 are to be moulded or otherwise formed of selectedmaterial which will afford the qualities of resiliency and durability.

The elasticity of the bands 13 and 1% permits the armor to be readilymounted and demounted.

The employment of non-metallic means for connecting the sections 10together, eliminates heating of the armor. The fact that the armor isnot attached in any manner to the tire it protects, or to the wheelwhich is equipped with the tire more than compensates the difference ofstrength of metal over rubber, the material used for the bands 18 and14:. There is very little strain on the bands, aside from the strain dueto irregularities of the road surface.

lVhat is claimed is;

1. An armor for pneumatic tires comprising interconnected sectionsdisposed normally end to end in contiguous relation, and elastic bandsextending through the sections permitting relative movement of thesections with respect to each other.

2. An armor for pneumatic tires comprising resilient sections, andcontinuous elastic bands extending through said sections, and connectingsaid sections together, the said sections being disposed end to endcontiguous each other as their normal relation.

In testimony whereof I hereby affix my signature.

STEPHEN ANDREW S.
